have you also read throw the httpd manual?
http://httpd.apache.org/docs/2.2/filter.html

perhaps take a look at mod_substitute docu and its source:
http://httpd.apache.org/docs/2.2/mod/mod_substitute.html

maybe this docu is also helpful:
http://httpd.apache.org/docs/2.2/mod/mod_filter.html

two other small filter modules are in ./modules/experimental ...
